Merge develop into main (#313)

- Add app path get() functions to `TactilityC`
- Improved `Dispatcher` and `DispatcherThread`
- Improved `PubSub` (type safety)
- Created test for `DispatcherThread` and `PubSub`
- Save properties files on app exit (various apps) by posting it to the main dispatcher (fixes UI hanging briefly on app exit)
- Fixed bug with `SystemSettings` being read from the wrong file path.
- `loadPropertiesFile()` now uses `file::readLines()` instead of doing that manually
- Increased timer task stack size (required due to issues when reading a properties file for the very first time)
- General cleanup
- Created `EstimatedPower` driver that uses an ADC pin to measure voltage and estimate the battery charge that is left.
- Cleanup of T-Deck board (updated to new style)
